These breeds are known for their strong-willed and independent personalities, which can make them more difficult to train. Additionally, some breeds may have smaller bladders or more frequent urination needs, which can make it more challenging to establish a consistent potty schedule.
However, it's important to note that any dog can be potty trained with patience, consistency, and positive reinforcement. The difficulty level may vary from breed to breed, but it is certainly achievable with the right approach.
